Abstract
A method for making an ink jet recording element comprising simultaneously coating on a support the following layers in order: a) a nonionic, water-dispersible, condensation polymer gloss-enhancing layer; and b) an ink receptive layer for an ink jet image.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A method for making an ink jet recording element comprising simultaneously coating on a support the following layers in order: a) a nonionic, water-dispersible, condensation polymer gloss-enhancing layer; and b) an ink receptive layer for an ink jet image.
2. The process of claim 1 wherein said support is paper.
3. The process of claim 1 wherein said ink receptive layer comprises gelatin.
4. The process of claim 1 wherein said ink receptive layer is present in an amount of from about 5 to about 60 μm.
5. The process of claim 1 wherein said gloss-enhancing layer is present at a thickness of from about 2 to about 5 μm.
6. The process of claim 1 wherein said condensation polymer is a block copolymer of a polyester and a polyether.
7. The process of claim 6 wherein said block copolymer is poly[terephthalic acid-co-isophthalic acid-co-ethylene glycol-block-poly(ethylene glycol)].
8. The process of claim 1 wherein an overcoat layer c) is also simultaneously coated with layers a) and b).
9. The process of claim 8 wherein said overcoat layer comprises a cationically-modified cellulose ether.
10. The process of claim 9 wherein said cationically-modified cellulose ether is poly[β-D-1,4-anhydroglucose-g-oxyethylene-g-(2'-hydroxypropyl)-N,N-dimethyl-N-dodecylammonium chloride].Cited by (0)
